Stegan (edma2)
From Just Solve the File Format Problem
stegan by edma2 (Eugene Ma) is a very basic open source Python steganography library for hiding data in 24-bit PNG images.
The Python Imaging Library models each pixel as a 3 element list, each corresponding to the value of an RGB channel. So, it just randomly chooses an array index from 0 to 2, for each pixel
It encodes 1 bit per 4-byte pixel so it can store just 1/32 of the host image size.
